Various fixes: - Put kdesupport11 dependency back. I forgot that it is not
implied by kdelibs11 as kdesupport2 is by kdelibs2. - HAS_CONFIGURE ->
GNU_CONFIGURE in some cases were needed. - Add X11 headers to CPPFLAGS for
moonshine (extreme case).

Overhaul QT/KDE support: - bsd.port.mk update to use bsd.kde.mk for
USE_{QT,KDE}* - Cleanup corresponding ports for bsd.kde.mk update. - Fix
bsd.kde.mk: use correct kdelibs dependency, put qt at the bottom, introduce
QT_NONSTANDARD variable for nonstandard configure setup. - Update KDE2 to
2.1.1. Two patches included in x11/kdelibs2 to fix the proxy authentication
that was broken for 2.1.1. Remove old patches. - Potentially fix kdelibs
build for alpha. - Fix qt-designer 2.3.0 build. - Ruby stuff left alone
since it looks like black magic to me. Should still work w/ compat shims
for older USE_QT[,2] style. Some others were also left alone for the same
reason.
